The BIP com- munication protocol divides the potential 255 addresses on the SLC loops into 8 groups of 32 addresses each and Card Cage Backplane the panel constantly samples the groups for fire signa- tures. Once a fire signature is detected, the panel nar- rows down to the group with the SmartOne device(s) initiating the signature and further to the particular address initiating the fire signature. The SmartOne smoke detectors manage their individual drift compensation routines, and have pre-alarm and •• alarm thresholds that are configurable in 0.1 percent-per- foot increments throughout the entire range of listed sen- sitivities.
